By Euprime B. Regalado From Gauss theorem, we can show that the surface of a curved charged conductor, the normal derivative of the electric field is given by where and are the principal radii of curvature of the surface. Gauss’s law in integral form is expressed as when there are no charges enclosed in the […]

Applying and in Proving the Vector Formula: By: Quennie J. Paylaga Prove: using Kronecker Delta Function and Levi-Civita Symbol. To prove this, we let We can write the expression for in summation form as: where where i, j, l are dummy summation variables. Each of which can be any letter […]
